LANTERN'.

Application led. December 9, 1921.

To @ZZ whom 'it may concern.'

Be it known that l, JOHN C. Fnosrnnn, a citizen oi' the United States,residing at Duluth, in the county oit St. Louis and State ot'li/iiiinesota, have invented certain new and usetul Improvements inLanterns, of which the following is a specification, reiference being'had therein to the accompanying drawing.

rlhie invention relates to lanterns and has special reference to oneused as a signal light by trainmen or the like.

rlhe principal object is to produce a lantern ot 'this character whichwill cast but a small amount ont shadow trom the bottom thereoll whenused tor signalling purposes.

Other objects and advantages ot the novel structure Will appear in thefurther description ot the invention.

Referring to the accompanying drawing forming wart of this applicationin which like reierence characters indicate like parts:

Figure l is a side elevation ol one et the improved lanterns showing oneembodiment oi the invention;

Figure 2 is an enlarged vertical sectional view through the base portionof the lantern, and

Figure 3 is a horizontal sectional View on the line 3--3 Figure 2.

The base or body portion l of the lantern is cylindrical in 'form andelongated vertically and made as small in diameter as possibleconsistent With the proper feeding of the oil and housing' `of the Wickof the lantern. There are holes or openings 2 in the opposite sides ofthe body portion l and practically midway of its ends and about whichholes are securely attached as by f-soldering or otherwise the terminalsot the tubular 'combination handle and oil container 3. gracefullyupnf'ardly and over the top 0i' the lantern, forming a convenientlyshaped handle.

Within the lower end of the body member l and normally extendingupwardly therewithin beyond the openings Q. is the adjustable sleeve t,terminating at its lower end in a closed cap lilre portion 5, by whichit may be readily manipulated. Adjacent the cap 5, upon thecircumferential Wall of the sleeve, is a screw-threaded portion,indicated at 6, by which it is held Within the body port-ion l. llthisscrew threaded portion is designed to t snugly so that the Speccation ofLetters Patent.

sleeve may be adjusted axially Within the body portion and remain in anydesired predetermined position. The object oi such adjustment is toprovide `lor the possibility of turning the sleeve et so that the largeropposed holes or openings .7 in the side Walls thereof may be made tocommunicate with the two ends or' the tubular member 3 when it becomesdesirable to flood the Wiel; chamber, or the sleeve may be adjusted aquarter turn either Way so that the smaller opposed holes 8 may be madeto communicate With the oil chamber, this adjustment being necessary forthe normalV Working of the lantern.

Within the upper end ot the body portion l is a screw threaded,cylindrieally shaped, chambered, burner 9, through and to which the Wickstack l0 is attached, it being provided with the usual means for raisingand lowering the Wick, About the burner chamber 9 and spaced slightlytherefrom is an annular Wall ll through Which are formed a plurality ontair supply holes 12 and above these holes Vand :termed integral With theWall ll is an annular rim or flange 13 upon Which rests the chimney letol the lantern. The space intermediate of the upper edge et the annularWall l1 and the Wall ot the chamber 9 is leit open so that the aircoming in through the holes l2 is supplied therethrough to the interiorof the lantern chimney. Y

Dovvnivardly arched supporting legs l5 are rigidly fixed to the lowerportions ot' the tubular member 3 adjacent the body portion l and thelower ends or teet oi these legs, together with similarly shaped legs l@et the guards 17, are mounted as by soldering or the like upon theannularly shaped Wire 18, forming a convenient, open base for thelantern.

lt Will be noted that there is no external opening Whatever to thetubular member 3 except through the body portion l, and that the lanternhas to be inverted in order to be lled which is simply accomplished bythe unscrewing of the sleeve 4f, and that in the event of the use ofdifferent grades o" signal oil the sleeve may be adjusted to thedifferent sized openings therein, as previously described, to providefor the proper feeding of same to the Wick.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

icov

1. A signal lantern of thereharaeter de scribed including a tubularcombined .handle and tank vertically sourrounding the 1antern.

2. Ak signal lanterniof the `character del.`

y tively small body portion, a burner `niounted upon the body portion, aCombination tubular handle and reservoir communicating With'the bodyportion and means Within the latter for regulating the flow of oil to beconsumed, and an open base about and extending below the body portion,substantially as and for the purpose described;

In testimonywhereof l hereunto affix my signature in the presence of tWoWitnesses.
